Calculate the Right Whole House Fan for Your Home
No one likes a surprise power bill at the end of the month due to an overloaded A/C unit. As outside temperatures increase, it’s time to think about cooling your home efficiently and effectively. Our Whole House Fans replace warm, stale indoor air with cool, fresh outdoor air. This process is called Thermal Mass Cooling. Fresh, cool nighttime air is brought in from outdoors to precool the house and its contents. Use our whole house fan sizing calculator below to find the right fan for your home. Once you have determined the necessary CFM for the home, choose from one of our Field Controls Whole House Fans, Tahoe or Summit.
Calculate the Model to Fit Your Needs
Enter the information in the whole house fan sizing calculator to reveal your Airflow CFM (Cubic Feet per Minute) then choose a whole house fan to fit your needs. Please note, CFM tells you how much air is moving per minute through the area. For example, one CFM equals one cubic foot of air moved per minute.
Tahoe Series
CFM: 5 different models available from 2,369 – 5,951 CFM
Summit Series
5 different models available from 2,576 – 6,065 CFM

Explore Our Fan Series
Field Controls offers two powerful whole house fan options, the Tahoe Series and the Summit Series. Each series is engineered for energy-efficient, whole home cooling. The Tahoe Series features a reliable PSC (permanent split capacitor) motor, delivering consistent airflow performance with simple, cost-effective operation. The Summit Series is built with advanced ECM (electronically commutated motor) technology, offering superior energy efficiency, quieter performance, and variable speed control. Both series are designed to quickly exhaust hot, stale indoor air and draw in fresh outdoor air which makes them ideal solutions for homeowners seeking comfort, ventilation, and energy savings. Once you have run the whole house fan sizing calculator, then choose the fan that is right for you.
